Application filed. March 13, 1908. Serial No. 420,939.

T 0 all whom it may concern:

Be it known that I, EDWARD O. CAPPER, a citizen of the United States, residing at Alha, in the county of Fayette and State of 5 owa, have invented a new and useful Device for Paraffining Vessels, of which the following is a specification.

The object of my invention is to provide a device of sim le, durable and inexpensive construction, designed to contain a quantity of parafiin, which paraffin may be maintained in a melted condition by means of steam or hot air, and which may be sprayed by the steam or hot air, over an inverted vessel resting on a support above the melted paraflin, and a further object is to provide improved and simplified means for heating the vessel to be coated with paraffin, prior to its being placed in position over the paraflin vessel, so that when the paraifin is sprayed on it, the coating of parafiin that will adhere to the vessel will be thin and evenly distributed.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of a device embodying my invention, with the cover in its closed position. Fig. 2 shows a vertical central sectional view of same, with the cover in its open position, and with the vessel to be coated laced on top of the parafiin receptacle. ig. 3 shows a detail view illustrating a portion of the cover with the steam pifpe opening therein, and the ivoted cap or covering said opening,and i 4 shows a detail perspective view illustratmg the detachable vessel supporting collars.

Referrin to the accompanyin drawings, I have use the reference numera 10 to indicate the paraffin receptacle. This is preferably cast complete in one piece of metal, and is tapered from its upper toward its lower end, and is provided with a horizontal partition 11 s aced apart from the bottom of the receptac e to form a heating chamber 12.

At one side of the vessel near its to are the lugs 13, and hinged to the vessel a jacent to the lugs is a cover 14. Said cover is provided with lugs 15 so arranged that when the cover is swung open to a substantially horizontal position, the lugs 15 and 13 will enga e and support the cover in a substantiaIly horizontal position. is provided with an opening 16 and with a pivoted cap 17 adjacent to the opening, whereby the opening may be closed when desired. A vent pi e 18 extends from the interior of the pared-En receptacle to a point of discharge.

It is intended that the parafiin or other substance to be used in coating vessels, shall be placed on top of the partition 11, and melted by means of steam or hot air admitted below the artition. In order to provide for withdrawing the melted paraflin from the paraffin receptacle, I provide a pipe 19 extending through the partition 11 and the bottom of the paraflining receptacle, and provided with a valve 20 at its lower end.

I11 order to provide for heating the paraflin receptacle, andfor spraying the melted parafiin and also for heating the vessel on top of the open cover, I employ a pipe 21 through which steam or hot air may be forced under pressure. A cut-off valve 22 is provided in said pipe, and a branch 23 connects with the pipe 21 and discharges into the chamber 12.

In order to provide for the escape of steam from the chamber 12, I employ a pipe 24 communicating with the chamber, and leading to a point of discharge, and provided with a valve 25, whereby the passage-way through the pipe 24 may be closed.

For spraying the paraffin, I have provided a branch pipe 26 communicating with the pipe 21 and extending up through the bottom of the vessel and through the partition 11, to a point a slight distance above said partition. A valve 27 is provided in said pipe controlled by a rod 28 extended outwardly beyond the bottom of the vessel, where it may be conveniently grasped by the operator.

I provide for heating a vessel resting on top of the cover when open, as follows: The numeral 29 indicates a branch pipe communicating with the pipe 21, and extending upwardly and designed to pass through the opening 16 in the cover, when the cover is in The said cover its open position, as clearly shown in Fig. 1. This branch pipe is provided with a valve 30, and at the bottom of the branch pipe 29 is a pet-cock 31 through which water of conden sation may be drawn off.

In order to adapt the paraffining device to fit vessels of various sizes, I have provided a series of vessel supporting collars. Each collar comprises an annular rim 32 and a second annular rim 33 below the first and extending inwardly. The outer collar is of such size that the annular rim 32 will rest on a shoulder near the top of the paraflining receptacle, as shown in Fi 2, and the vessel to be coated with paraffin is then placed on top of the annular rim 32. A number of collars of various sizes are provided, and so arranged that the annular rim 32 of one collar may rest on the annular rim 33 of another, as shown in Fig. 4 in such a manner as to provide a level surface on the top of all of the collars to receive vessels to be coated, so that vessels of any size may be accommodated.

In practical use, I first place a quantity of paraflin in the parafiining receptacle. I then open the valve 22 and permit steam to enter the chamber 12. The air within the chamber may be drawn ofi through the pipe 24. The heat in the chamber 12 will cause the paraflin to be melted. The cover is placed in an open position, and an inverted vessel is placed thereon, as shown in Fig. 2, then the valve 30 is opened, and steam is admitted into the vessel to heat it. Then the heated vessel is placed upon one of the collars on top of the paraifimng vessel, and the valve 27 is then opened, so that the steam under pressure will blow up through the parailining and cause it to be sprayed over the interior of the vessel to be paraflined. The steam escapes through the pipe 18.

When the spraying has continued long enough to properly coat the vessel, the valve 27 is closed. and the vessel removed. Obviously, one vessel may be heated upon the cover while the other is being coated over the paraflining receptacle, so that an operator may quickly and easily heat and parafin a large number of vessels. The melted paralfin may be if desired, withdrawn through the pipe 19.

When not in use, the cover may be closed over the paraflining receptacle, as shown in Fig. 1, and the cap 17 placed over the opening 16 so as to exclude dust from the interior of the paraifining receptacle.

I do not desire to be understood as limiting myself to the use of paraffin as the coating material nor to the use of steam as the heating material, as it is obvious that any suitable coating material may be used on a device of this kind, and any suitable heating medium may be employed instead of steam.

Having thus described my invention, what I claim and desire to secure by Letters Patent 01 the United States, is

1. In a device of the class described, the combination of an open topped receptacle, a partition spaced apart from the bottom oi the receptacle, said vessel above the partition being designed to contain melted parallin or the like, means for introducing a heating medium into the space between the partition and the bottom of the receptacle, means for supporting an inverted'vessel at the top oil, the receptacle and above that portion of the receptacle designed to contain the parallin, and a pipe extending upwardly through the partition to a point a slight distance above it, a valve in said pipe, and means for supplying a heating medium under pressure to the pipe.
